Jo, a young woman and street circus artist, discovers the work of the professional clowns of “Nez pour Rire”. Quickly - perhaps too quickly - entering the association, she found herself at the hospital in contact with children, sick people, caregivers and families, to whom these clowns tirelessly try to bring joy and comfort. .

In a French public hospital, the adolescent psychiatry unit moves to the erratic rhythm of teenagers coming and going - many carrying heavy past baggage - while Etienne and his medical team navigate the relentless cycle of treating, listening, and confronting the raw edges of suffering. Young Lucia knows the ward too well. After being brought back yet again by the police, she reunites with her friend Eloïse and encounters a constellation of young patients, each wrestling with their own storms. At times, there is laughter, small breakthroughs, moments of fragile hope. But the balance is shaky, and the arrival of a new patient will shatter it entirely.
